'Be it known that I, S'rnA'rroRn B. ALLEN, of Cambridge, in the countyof Middlesex and State of Massachusetts, have invented certain new anduseful Improvements 1n Devices for Filling Drawing-Pens, of which thefollowing is a specification. I Y

This invention relates to a device for filling drawing pens.

The object of the invention is to provide a device by means of which adrawing pen may be quickly filled without smearing ink upon the outsideof the pen.

A further object of the invention is to provide means for quicklycleaning the pen of dried ink. I

A still further object isto provide a convenient supply of absorbentmaterial to remove any ink from the outside of'the pen in case someshould be "spilled thereon.-

I will describe my invention in the following specification and pointout the novel features thereof in the appended claims.

In'the accompanying "drawing, Figure 1 is a sectional elevation of thedevice complete showing the method of filling a ruling pen, and Fig. 2is a plan view ofthe device.

As illustrated in the drawing the device comprises a cylindrical shell1, preferably of metal, set into a cap 2 having a hole 3 into which asmall tube 4 is inserted. The top of the shell 1 is closed by a cap 6,which fits said shell closely. The top cap 6 is provided with a fillinginlet, which is closed by a removable plug 8, and said cap is alsoprovided with a screw threaded bushing 10, which forms a guide for theupper end of a valve stem or rod 12. Aflixed to the lower end of thevalve stem 12 is a metal disk 14,

which is faced on itsunder side with 'a disk of rubber or other suitablematerial 16 and adapted to fit the outlet 3. Depending from r the lowerend of the valve stem, is a wire 18 disk 14 andthe inner end of thebushing 10.

The valve is raised from its seat by a bellcrank lever 22, fulcrumed at24 in cars 26 projecting laterally from the top. cap 6. The horizontalarm 28 of the lever 22 is adapted to engage the under side of, a head orbutton 30 on the upper end of the valve I I Specification of LettersPatent.

fingers 32, for guiding the pen 34 as it is said fingers being slightlyabove and in line with the discharge end of the tube 4.

- The ink reservoir, composed of the cylinder 1andcaps2 and6,is'moun'ted on a base 86, which is preferably made :of metal, and iscut away on one side to allow the nibs of the pen to be brought underthefilling tube 4.

Thus the outlet 3 and tube4 are opened, and the the space between the nibs of the pen 34,

of the valve stem moves back and forth obstruction formed by the dryingup and consequent hardening of exposed ink at the discharge end of saidtube. 2

The pen cleaner is composed of two strips of metal 40, 41, which mayconveniently be are bentto form a fork or guide for the pen. A thinpiece of brass or other metal 42 is held between the strips 40, 41,preferably by a screw 44. To clean the pen it is inserted between thestrips 40, 41 with the metal strip42 between the nibs, then the penisdrawn upward and the strip 42 passes between the two points ofthe pen,forcing out any dried ink or foreign matter lodged therein. The penwiper is conveniently mounted on tube 50 slotted throughone side as at52 and set into a socket. 54 formed on the base 36, or the tube may bemade with a metal bottom. The tube is filled with disks 56 of The soiledpen is insertedthroughthe slot placed in filling position, the junctionof end of the tube 4 between the nibs of the pen.

While I have illustrated and described a preferred embodiment of theinvention, I am aware that many modifications can be made therein by anyperson skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore I do not wish to belimited to all the details of construction shown and described, but

lVhat I claim is l. A device for filling drawing pens, com prising anink reservoir provided with a discharge tube, a valve for controllingthe flow of ink through said discharge tube, and

a guide for the pen operatively connected to open said valve when thepen is moved into filling position.

2. A device for filling drawing pens, comprising an ink reservoirprovided with a discharge pipe communicating with its lower end, a valvefor controlling the flow of ink through said pipe, a lever connected tosaid valve, and a guide on said lever arranged to position the pen incorrect relation with the outlet of said discharge pipe when said valveis opened.

In testimony whereof I have aiiixed my signature, in presence of twowitnesses.
